PoQ and PQ verification surfaces

Public Verification Model

PoQ is advisory, non-consensus, and non-blocking unless a future explicit consensus change says otherwise. PQ/hybrid posture is explicit and should not be described as complete PQ coverage everywhere.

• talero_getPqNodeStatus gives node-wide PQ and PoQ posture.
• talero_getEvmPoqReadSurface gives a stricter EVM/off-chain consumer view.
• talero_getPoqProofFeed exposes latest and recent checkpoint proof feed data.
• talero_posBftGetPqFinalityExportBundle exposes exportable finality proof bundles when available.
• talero_getPoqEthereumAnchor prepares a descriptive Ethereum anchor payload. The node does not sign, submit, custody, bridge, or move assets.

Fail-Closed Meanings

• runtimeUsable=false: consumers should not rely on the PoQ/PQ surface for current decisions.
• currentCertificate.available=false: no usable current certificate is available.
• exportBundle.available=false: no exportable finality bundle should be displayed as available.
• anchorable=false: do not present the anchor payload as ready to anchor.
